Xi's senior foreign policy adviser, Yang Jiechi, says the two leaders "talked about cooperation and did not shy away from differences" in about eight hours of talks Friday and Saturday. The gathering at the sprawling Sunnylands estate was their first meeting since Xi took office in March.

Yang said the international community expects relations between the world's two largest economies to steadily improve and grow, and they are committed to working more closely together. He called it "a strategic, constructive and historic meeting."

US official: China, US aligned on North Korea

A top U.S. national security official says President Barack Obama and Chinese President Xi Jinping found "quite a bit of alignment" on the subject of North Korea and on the importance of keeping the communist nation from becoming a nuclear armed state.

White House national security adviser Tom Donilon says the common ground between Obama and Xi on North Korea provides a key for enhanced U.S.-China cooperation.

Donilon spoke Saturday at the end of two days of meeting between Obama and Xi in an estate in the California desert.

Obama outlines cyber problems for Chinese leader

President Barack Obama's national security adviser says the president described for China's leader the types of problems the U.S. has faced from cyber intrusions and theft of intellectual property.

White House national security adviser Tom Donilon gave no specifics but says Obama also underscored for Chinese President Xi Jinping (shee jihn-peeng) that the U.S. has no doubt that the intrusions are coming from inside China.

Donilon says Obama requested that the Chinese government "engage" on the issue and also understand that that type of activity is inconsistent with the kind of relationship U.S. desires to build with China.

Donilon addressed reporters Saturday after Obama and Xi concluded two days of meetings at a resort in Rancho Mirage, Calif.
